The work aims to prepare the label composite film with good properties, anti-electrostatic performance and anti-counterfeiting performance in a convenient and economic way. With wood fiber as raw material, based on natural seasoning and magnetic field, the directional ferroferric oxide nano-particles (nano-Fe3O4)/nanocrystaline cellulose (CNCs) anti-electrostatic iridescence anti-counterfeiting composite film was prepared. Composite film four-probe specific conductance, polarizing microscope, scanning electron microscope, attenuated total reflection Fourier infrared spectrum and X-ray diffraction spectrum, etc. were comprehensively analyzed. The testing showed that adding nano-Fe3O4 and magnetic field orientation could improve the film’s conductivity without preventing CNCs cholesteric liquid crystal self-assembly from forming colorful pattern, besides, the best mass ratio of CNCs and Fe3O4 was 20∶1 when the composite film had the best effect. This label film has anti-electrostatic performance and anti-counterfeiting performance, and it has certain application value for packaging anti-counterfeiting.
